+### Preparing Models for Databases API
+
+For the .NET SDK, we use the `Newtonsoft.Json` library for serialization/deserialization support. The default behavior converts property names from `PascalCase` to `camelCase` on serializing to JSON. In case the names of attributes in your Appwrite collection are not created in `camelCase`, this serializer behavior can cause errors due to mismatches in the names in the serialized JSON and the actual attribute names in your collection.
+
+The way to fix this is to add the `JsonProperty` attribute to the properties in the POCO class you create for your model.
+
+For e.g., if you have two attributes, `name` (`string` type) and `release_date` (`DateTime` type), your POCO class would be created as follows:
+
+```csharp
+public class TestModel
+{
+  [JsonProperty("name")]
+  public string Name { get; set; }
+
+  [JsonProperty("release_date")]
+  public DateTime ReleaseDate { get; set; }
+}
+```
+
+The `JsonProperty` attribute will ensure that your data object for the Appwrite database is serialized with the correct names.
